Creating optical illusions is an art in itself. And portraying an optical illusion into an aesthetically pleasing work of art requires a fair bit of sense and sensibility. Expressing your artistic skills through illusions calls for the stroke of genius. Literally. In today’s post featured artists have shown their mastery of artistic shapes and colors to produce enlightening as well as scary optical illusions. The post also includes some awesome 3D optical illusions and Jesus optical illusion pictures

OPTICAL AMPLIFIER An optical amplifier is a device that amplifies an optical signal directly‚ without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity‚ or one in which feedback from the cavity is suppressed. Optical amplifiers are important in optical communication and laser physics. There are several different physical mechanisms that can be used to amplify a light signal‚ which correspond to the major types of optical

Optical Computing Jainam Shah Kalol Institute Of Technology‚ Kalol‚ Gujarat‚ India. jainam_8888@yahoo.co.in Abstract—Optics has been used in computing for a number of years but the main emphasis has been and continues to be to link portions of computers‚ for communications‚ or more intrinsically in devices that have some optical application or component (optical pattern recognition‚ etc). Optical digital computers are still some years away‚ however a number of devices that can ultimately lead to

State the characteristics of optical fiber communication. Why we Use Optics for Computing? One of the theoretical limits on how fast a computer can function is given by Einstein’s principle that “signal cannot propagate

Rachel Hahn Cheryl Blackwell Seminar November 2012 Optical Illusions An illusion is the distorted perception of a stimulus. They are not to be confused with hallucinations‚ which are false perceptions when there is no presence of a stimulus‚ in contrast‚ illusions are the misinterpretation of a true sensation (Illusion Wikipedia). Illusions are mundane phenomena‚ and are experienced by nearly everyone in similar ways where hallucinations are a personal experience and are typically limited

[pic] An optical illusion also called a visual illusion is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed in the brain to give a percept that does not tally with a physical measurement of the stimulus source. There are three main types: literal optical illusions that create images that are different from the objects that make them‚ physiological ones that are the effects on the eyes and brain of excessive stimulation

The telescope is an important astronomical tool that gathers and focuses electromagnetic radiation. Telescopes serve to both increase the angular size and the brightness of objects. When we speak about telescopes we are usually referring to optical telescopes‚ but many other types of telescopes also exist for other spectrum of electromagnetic radiation. It is unclear as to who it was that actually invented the telescope but Galileo Galilei is credited as being the first to use a telescope for
